Understand Not all calories are created equal Reduce risk of
chronic diseases; CVD, DM, Hypertension, Cancer, Enhance Immune
system Better Engine, Better Energy Track Health Markers blood
work, measurements Promote Healthy Lifestyle 24/7

be your food." Hippocrates
- Slide 6
- Diet & Genetics
- Slide 7
- Its a Journey
- Slide 8
- Genetics & Nutrients Genes are turned on and off by
regulatory genes, and regulatory genes are controlled mainly by
nutrients, there are no drugs anywhere that can regulate genetic
expression better or more powerful than diet.

higher lipid profile (cholesterol, TG, LDL), poor mood/brain
health.

(step 1) vs. Mediterranean (MED) Followed over 4 years, n= 605
prior MI (heart attack) patients Subjects: same blood pressure,
BMI, smoking status, lipid profile. < 70 yr Objective: Measure
the rate of cardiovascular complications after 1st heart attack
Results: Same lipids; total cholesterol, LDL, HDL. TG levels.bwtn
both groups
- Slide 39
- More Results Mediterranean group had 70% fewer CV events (fatal
& non fatal heart attacks) 56% fewer deaths 61% fewer cancers
Why? Less red meat, Higher antioxidants, Higher omega 3s.lower
